Application filed November 25, 1931. Serial No. 577,185.

The objects of the invention are:

First, to provide a very simple and eflicient means of supporting andsecuring the tank in place on the closet bowl shelf.

5 Objects pertaining to details will appear from the description tofollow. Apreferred embodiment of my invention is illustrated inthe'accompanying drawing, in which:

Fig. 1 is a vertical longitudinal central section through a water closetbowl and tank embodying the features of my invention.

Fig. 2 is a detail vertical sectional view through the connectingmeansbetween the bowl and tank, taken on line 22 of F ig 1. Fig. 3 is anenlarged detail of the packing jointsurrounding the outlet from thetank.

Fig. 4 is a plan view of the specially constructed washer. Fig. 5 is asectional viewon line 5.5 0f 4, showing the details of the cross section of the said washer before it is compressed.

The parts will be identified by their numerals of reference. I t 1 isthe water closet bdwl with the rear wardly projecting hollow shelf 2 forsupporting and attaching the tank. This is pro.-

vided with supporting side walls 22 which form a recess 23 entirelyconcealing from view the attaching screw hereafter to be described.

j 3 is the tank of vitreous china material supported on the said shelf,there being a ground j oint 5 on the bottom of the tank fitting acorresponding ground joint 51 on the top of the shelf of the bowl; 4 isthe usual flush valve construction, the screw threaded shank 41 of whichprojects well below .the bottom in the usual manner and projects into man opening in the top'wall of the shelf.

6 is a special nut for attaching the said.

flush valve structure, threaded to engage the projecting shank .41 andthus support the flush valve structure in theiusual way. The

nut is provided with a downwardly projecting cross bar 61 having athreaded boss 62 1 at the center. Attaching screw 7 projects upwardlythrough the lowerpwall of the shelf and engages the said threaded boss62.

This screw 7 is centrally located and is embraced and concealed in therecess 23 at the back of said bowl. A metal washer 71 is provided whichengages a rubber packing washer 72 to securely close the opening atthatpoint. A specially constructed packing washer 8 is disposed betweenthe flange 68 and in a seat 11 formed in the top of the shelf.

This washer is' provided with a clownwardly outwardly projecting flange8 1 which engages in the lower periphery of the seat' and by this means,adjusts itself to contact with the side w ll of the seat, no matter whatvariation in size there may be due to the shrinking of the china in thefire. The washer 8 is notched at 82 to pass readily up over the crossbar 61.

It will thus be seen'from this description that I have rovided avitreous bowl and a vitreous tan which is very readily and securelyclamped in place on said bowl by the single screw'shown. The parts arecompletely and effectively sealed water tight by the action of the saidscrew. The structure is simple and very economical to produce. Thewasher I have shown between the parts is of special construction andvery effective. I

I desire to claim the same specifically in this relation, and I alsodesire to claim the invention broadly, as pointed out in the appendedclaims.

Having thus described my invention, what I claim as new and LettersPatent is: V I

1. The combination of a vitreous bowl water closet having a rearwardlyprojecting a round 'joint surface on v hollow shelf with the top havinga pac ng seat therewithin, a' vitreous tank having a joint surfacecorrespondinglthereto, a usual flush valve structure wit in the tankhavinga projecting screw shank below the bottom thereof, a nut with aflanged tgp for engaging the same desire to secure by having a cross barwith a central boss having a screw threaded aperture, a packing washerbetween said flange and bowl having an .out-

wardly downwar ly projecting flange to engage said seat, an attachingscrew disposed through an aperture in the said shelf'and 'engaglng thesaid boss, and a washer and' packing therefor.

2. The combination of a vitreous bowl water closet having a rearwardlyprojecting hollow shelf with a joint surface on the top having a packingseat therewithin, a vitre- 5 bus tank having a joint surfacecorresponding. thereto, a usual flush valve structure within the tankhaving a projecting screw shank below the bottom thereof, a nut with aflanged top for engaging the same having across bar with a central bosshaving "a screw threaded aperture, a packing, washer between said flangeand bowl having an outwardly downwar 1y projecting flangeto engage saidseat, an attaching screw disposed through an aperture in the said shelfand engaging the\ said boss, and a packing therefore i '3. 1hecombination of a vitreous'bowl water closet having a rearwardlyprojecting hollow shelf with a joint surface on the top havin a packingseat therewithin, a vitreous tank avifig a joint surface correspondingthereto, a usual flush valve structure within the tank having aprojecting screw shank below the bottom thereof,anut with -aflanged topfor engaging the same having a cross bar with a central boss having ascrew. threaded aperture, apacking washer between said flange and bowl,an attaching screw disposed through an aperture in the said shelf andengaging the said boss, and a pack-' ing therefor. i 4. The combinationof a vitreous bowl water closet having a 'rearwardly projecting hollowshelf with side walls supporting the same forming a concealed recess atthe back, and a vitreous tank adapted to be supported on saidshelf andsecured by an attaching. means comprising a central screw concealed 40in the said recess.

In witness .whereof'I'have-hereunto set my hand. 4
